What is the area of a circle with a diameter of 6 Cm?
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle. Since the diameter is twice the length of the radius, the radius of a circle with a diameter of 6 cm is 3 cm. Plugging this value into the formula, we get A = π(3)^2 = 9π cm^2. Therefore, the area of a circle with a diameter of 6 cm is 9π square centimeters.
What is the area of a circle whose diameter is 20 cm?
The formula to calculate the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter is 20 cm, the radius would be half of that, which is 10 cm. Plugging in the radius into the formula, we get A = π(10)^2 = 100π cm^2. Therefore, the area of the circle with a diameter of 20 cm is 100π square centimeters.
What is the radius of a 2 cm circle?
The radius of a circle is half the diameter, so if the circle has a diameter of 2 cm, the radius would be 1 cm.
What is the diameter of a circle whose area is 314 cm square?
To find the diameter of a circle with a given area, you first need to calculate the radius using the formula for the area of a circle: A = πr^2. Given that the area is 314 cm^2, you can rearrange the formula to solve for the radius, which would be √(A/π). Plugging in the area, you get √(314/π) ≈ 10 cm. Finally, to find the diameter, you double the radius, resulting in a diameter of approximately 20 cm.
What is the radius of a circle with a 6.2 cm diameter?
The radius (radii) of a circle is 1/2 of the diameter. The radius of a circle with a 6.2 cm diameter is 3.1 cm.
